Casein and whey protein were hydrolyzed using 11 different commercially available enzyme preparations. Emulsion-forming ability and emulsion stability of the digests were measured as well as biochemical properties with the objective to study the relations between hydrolysate characteristics and emulsion properties. All whey protein hydrolysates formed emulsions with bimodal droplet size distrib...

Leucine has been suggested to have the potential to modulate muscle protein metabolism by increasing muscle protein synthesis. The objective of this study was to investigate the surplus value of the co-ingestion of free leucine with protein hydrolysate and carbohydrate following physical activity in elderly men. Eight elderly men (mean age 73 +/- 1 years) were randomly assigned to two cross-ove...

The aim of this study was focused on investigating the effects of chemical modifications and molecular weight distribution of phytate-removal Soybean Protein Isolate (SPI) hydrolysate on Degree of Hydrolysis (DH) and the iron binding ability. The chemical modifications included acid treatments, succinylation, acetylation and phosphorylation. Also the effects of molecular weight distribution of ...

Abstract Nile tilapia skin is one of the wastes produced by fillet industry that contains quite high protein. One form utilization very potential gelatin, which known to have bioactive when hydrolyzed properly. The choice Flavorzyme as a hydrolyzing agent because it can hydrolyze proteins specifically and does not cause damage. result gelatin hydrolysis flavorzyme at 50°C was hydrolysate liquid...

Egg-yolk protein hydrolysate (YPp) is an alternative protein source in formulas for infants with intolerance to cow's milk or soyabean protein, or for patients with intestinal disorders. However, the nutritional value of YPp has never been investigated. YPp was prepared by enzymic hydrolysis of delipidated yolk protein, which led to an average peptide length of 2.6 residues. Three experiments w...

Following cross-linking by microbial transglutaminase, modified oyster proteins were hydrolyzed to improve inhibitory activity against angiotensin-converting enzyme (ACE) inhibitory activity with the use of a single protease, or a combination of six proteases. The oyster hydrolysate with the lowest 50% ACE inhibitory concentration (IC50) of 0.40 mg/mL was obtained by two-step hydrolysis of the ...

The hypothesis that dietary proteins or their hydrolysates may regulate intestinal mucin discharge was investigated in the isolated vascularly perfused rat jejunum using an enzyme-linked immunosorbent assay for rat intestinal mucins. On luminal administration, casein hydrolysate [0.05-5% (wt/vol)] stimulated mucin secretion in rat jejunum (maximal response at 417% of controls). Lactalbumin hydr...

BACKGROUND The main objective of this experiment was optimal use of none edible protein source to increase nutritional value of production with high biological function, including antioxidant activity. METHODS Sheep visceral (stomach and intestine) was used as substrate. Response surface methodology (RSM) was used to optimize hydrolysis conditions for preparing protein hydrolysate from the sh...

This study was carried out to evaluate the efficiency of natural protease extracted from starfruit (Averrhoa carambola. L) to hydrolyse green mussel (Perna viridis). Starfruit juice from fruit of maturity index 2 was extracted and purified using acetone precipitation method. The obtained protease was then used to hydrolyse green mussel and compared with alcalase. The conditions used to produce ...

The poor growth of aquatic animals fed with diets containing high plant proteins has been attributed to low diet acceptability and feed value. Supplementation protein hydrolysate, contents free amino acids soluble molecular weight peptides, may increase the value a protein-based diet. In present work, squid processing by-products were enzymatically hydrolyzed used as supplement in diet, without...
